Good morning, commuters! A layer of snow and ice still coats the ground in many areas, but as the work week begins another wintry problem has emerged thanks to freezing rain falling overnight and into early Monday morning.

Freezing rain or a freezing drizzle could cause icing and slick spots, particularly on untreated or elevated surfaces, according to the Capital Weather Gang. Areas north and west of the Beltway are the likeliest candidates for slick spots on Monday morning, because temperatures will take the longest to rise above freezing.

The freezing fog and drizzle will eventually transition into normal scattered rain showers, according to the Capital Weather Gang. But this morning’s commute is going to be very tricky. Use extreme caution when you head out this morning. If you’re driving, riding a bicycle or walking to a train station, make sure to be careful and not to rush. Untreated roads, sidewalks, train station stairs and other surfaces will be slick and slippery.

The federal government isn’t opening until 11 a.m. on Monday, and federal employees are being encouraged to stay off the roads until 9 a.m. due to the icy conditions. This is going to greatly lessen crowding during the normal rush hour window, but it also means there will be a heavier commuter presence between 9 and 11 a.m. If you normally head to work during this time, watch out for greater congestion.

Metro is running expanded rush hour service due to the federal government’s delayed opening. Metrorail and Metrobus will run additional trips during the late morning hours, while Metro has canceled all midday track work scheduled for Monday.

The Fairfax Connector is running normal service and extending rush hour service through 11:30 a.m.

Alexandria’s DASH bus system will also run for an extra two hours during the morning rush hour due to the federal government’s delayed opening.

The Virginia Railway Express will operate on its normal schedule, as will Montgomery County’s Ride On buses. Arlington Transit is also running normal service.

We’ll be keeping an eye on the roads and rails this morning, reporting any delays or issues — and we will need your help. If you hear about any congestion, delays, problems or anything at all, tell us in the comments section below or by tweeting @drgridlock.

And if you’re driving this morning, make sure to clear the ice off of your car before heading out. Big chunks of ice falling from a car while driving can be extremely dangerous yet is always avoidable.
